To all whom it may concern.'

Be it known that I, BRUCE FDRD, a citizen of the United States, residin at Philadelphia, in the county of Phi adelphia and State of Pennsylvania, have invented oertain new and useful Improvements in Electric Storage Batteries, of which the followmg is a specification.

he princlpal object of the present invention is to provide for safely hoisting complete or assembled cells which in the case of submarine and like batteries are very heavy and are contained in jars of insulating material ossessed of little tensile strength.

Ot er objects of the invention will appear from the following description and the invention will be claimed at the end hereof but an embodiment of the invention will first be described in connection with the accompanying drawing forming part hereof and which is a view rincipally 1n section.

In the rawng. 1, is a reinforcenlrent having at its lower edge a seat 2, which may be undercut. The reinforcement 1, is arranged at the top of the opposed Walls, usually the end walls of the )ar and extends well below the ledge 4, upon which is seated the bus-bar 5, from which the plates 6, depend. The reinforcement 1, and the jar Wall 3, are of molded insulating material which is known to he of little tensile strength. Hard rubber and equivalent substances are examples of such material. 7, is a hook which engages the seat 2, and the lifting stress of the hook is resisted by the compression or shearing strength of the considerable mass of material provided vertically between the ridge 4 and the seat 2, by the reinforcement 1. The hook 7, depends from one rnd of a yoke 8, centrally provided with an opening 9, which is a means by which the yoke can lm connected with hoisting tackle. lt will be understood that in the drawings and dcscription reference is made to only one-half the arrangement, but from this the other and dupiirate half will be readily understood. The hook i", normally has an uwarfl set, as shown in dotted lines so that it tends to remain in engagement with the seat 2. Moreover the hook is shown as detachably connected with the yoke 8, which is a matterh of convenience in ackin `and storng. In any event the Weig t of t e jar and electrol te contained in it is carried by the reinorcement and to this load there is frequently added the Weight of the plates. 10, are bars depending from the yoke and they can be bolted to the terminals 11, not necessarily to carry any part of the weight of the plates, but to provide stability to the structure 7-8, principally in regard to lateral motion relative to the jar, and also to prevent the plate structure from falling in case of accidental failure of the hooks 7, so that in that case only the jar and electrolyte would falli.

What I clalm is:

1. A storage battery jar provided internally with a plate-supporting ledge, and provided at its top with a reinforcement having an undercut seat arranged on the outside of lthe jar and below the ledge, substantially as described.

2. The combination of a storage battery jar rovided internally with a plate-supporting ledge and provided at its top with a reinforcement having an undercut seat arran ed on the outside of the jar and below theedge, and a yoke having hooks for detachably engaging said seat.

3. The combination of a storage battery jar rovided internall with a plate-supporting ledge and provided at its top with a reinforcement having a seat arran ed on the outside of the jar and below the adge, and a yoke having hooks for detachably engaging said seat.

4. The combination of a storage battery jar provided internall with a, plate-supporting ledge and provided at its top with a reinforcement having a seat arran ed on the outside of the 'ar and below the ledge, and hooks for detac ably enga ing said seat.
